不饱和聚酯树脂与双马来酰亚胺的共聚改性研究

The Research of Modificating Unsaturated Polyester Resin By Copolymerizing Bismaleimide

介绍利用双马来酰亚胺（ＢＭＩ）作为共聚单体与不饱和聚酯（ＵＰ）树脂进行共聚反应，从而大幅度地提高材料玻璃化转变温度、弹性储能模量、拉伸和弯曲性能的方法，并通过实验加以分析验证。

The modification of an unsaturated polyester resin by copolymering thermosetting bismaleimide as a second co reactive monomer was studied. The resulting inter crosslinked network showed an obvious enhancement of the glass transition temperature, elastic modulus and strength.It had been testified by experiments.
